Gently, they break easily. They also make tools to R&R piston rings to avoid breaking the rings.

The DNJ ring spec. information, printed on each compression ring (located next to the piston ring gap), is installed facing the top of the piston for both the top (#1) and middle (#2) compression piston ring slots. The oil control ring can be installed just like any other oil control ring in the bottom (#3) piston ring slot.
The piston rings are fitted round the piston to make a better gas-tight fit in the cylinder.

Running an engine with broken piston rings will cause damaging scoring in the piston chamber, and is not to be recommended.
It is a spring metal sleeve that goes over a piston to compress the rings so that the piston can be install in the motor. It tightens down on the piston, forcing the rings into the grooves in the piston then you tap it into the cylinder.
